If you use three different guitars or three different amps on your gigs, this little routing pedal is a lifesaver. No more muting and unplugging your cable to switch between e.g. two electric and one acoustic guitar. Just connect it all to the ABC and route any three inputs to the same output – or any one input to three separate outputs.
PLEASE NOTE! DO NOT use on powered speaker lines. You WILL damage your amp, speakers or both!
